American Express is neither a Visa nor a Mastercard. Day to day, while Visa and Mastercard function as open-loop networks connecting thousands of different issuing banks to merchants, American Express acts as both the network and the primary issuer for the vast majority of its cards. Practically speaking, it operates as a completely separate, closed-loop payment network that issues its own cards and manages its own merchant relationships. This fundamental structural difference defines everything from where the card is accepted to the rewards structure and fee models cardholders experience.
Understanding the Payment Network Landscape
To understand where American Express fits, it helps to visualize the payment ecosystem. When you swipe, dip, or tap a credit card, a complex digital conversation happens in seconds between the merchant, the merchant’s bank (acquirer), the payment network, and the cardholder’s bank (issuer) Worth keeping that in mind. Still holds up..
Visa and Mastercard are networks only. They do not issue cards directly to consumers. Instead, they partner with financial institutions like Chase, Bank of America, Capital One, or Citi. These banks issue the cards, set the interest rates, determine the rewards, and bear the credit risk. Visa and Mastercard simply provide the "rails"—the communication infrastructure—that moves the transaction data and funds between the merchant and the issuing bank. They make money primarily by charging a small assessment fee on every transaction volume that runs on their rails Which is the point..
American Express is a closed-loop network. Historically, American Express issued its own cards directly to consumers and signed up merchants directly. There was no middleman bank issuing the card on Amex’s behalf. This means American Express controls the entire value chain: the brand, the network technology, the underwriting, the customer service, and the merchant relationships. Because they capture the economics of both the issuer side (interest, annual fees) and the network side (merchant discount rates), their business model differs significantly from the open-loop competitors.
The "Closed-Loop" vs. "Open-Loop" Distinction
This structural difference is the single most important factor for consumers to grasp.
Open-Loop (Visa / Mastercard)
- Four-Party System: Cardholder -> Issuing Bank -> Network (Visa/MC) -> Acquiring Bank -> Merchant.
- Ubiquity: Because thousands of banks issue Visa/MC cards, acceptance is nearly universal globally. If a merchant takes credit cards, they almost certainly take Visa and Mastercard.
- Standardization: Interchange fees (what the merchant pays) are largely standardized by the network, though they vary by card type (debit, credit, premium, commercial).
Closed-Loop (American Express / Discover)
- Three-Party System: Cardholder -> American Express (Network & Issuer) -> Merchant.
- Direct Relationship: Amex knows exactly who the cardholder is and who the merchant is. This allows for richer data capture, which fuels their premium rewards and targeted merchant offers (Amex Offers).
- Higher Merchant Fees: Historically, American Express charged merchants a higher discount rate (often 2.5% – 3.5%) compared to Visa/MC (often 1.5% – 2.5%). This is the primary reason some small businesses historically refused Amex.
- OptBlue Program: In recent years, Amex launched OptBlue, allowing third-party acquirers to set their own pricing for Amex acceptance. This has significantly lowered the barrier for small merchants and expanded acceptance dramatically.
Does Any Bank Issue American Express Cards?
Yes, but with caveats. While American Express is primarily a direct issuer, they do partner with select banks for co-branded cards or specific geographic markets.
- Co-Branded Partnerships: You will see cards like the Delta SkyMiles® Reserve American Express Card or the Hilton Honors American Express Surpass® Card. In these cases, the partner (Delta, Hilton, Marriott) influences the rewards currency and benefits, but American Express remains the issuing bank and the network. The statement says "American Express," and the customer service is Amex.
- International Issuers: In certain countries where Amex does not have a direct banking license or infrastructure, they license the brand to local banks (e.g., Santander in Mexico, NAB in Australia historically). These cards run on the Amex network but are issued and serviced by the local bank.
On the flip side, you will never see a card that says "Chase Visa" on one side and "American Express" on the other. A card runs on one network. Day to day, if the logo on the front is the blue box or the centurion, it runs on the American Express network. If the logo is the blue/white/gold "Visa" or the overlapping red/yellow circles "Mastercard," it runs on those respective networks.

Acceptance: The Real-World Impact
The most practical difference for a cardholder is acceptance.
Domestic Acceptance (United States)
The gap has closed significantly. According to recent Nilson Report data, American Express acceptance in the U.S. is now virtually on par with Visa and Mastercard at roughly 99% of merchants that accept credit cards. The OptBlue program was the catalyst. Large retailers (Amazon, Walmart, Target, Costco—though Costco is exclusive to Visa in-store) all take Amex. Most restaurants, gas stations, and online retailers accept it Most people skip this — try not to..
Exceptions: Some very small businesses, independent contractors, or specific government agencies (like some DMVs or tax offices) may still only take Visa/MC/Debit due to fee sensitivity or legacy terminal setups.
International Acceptance
This remains the weak spot for American Express.
- Visa/Mastercard: Accepted in over 200 countries and territories. They are the default global standard.
- American Express: Accepted in fewer countries (roughly 160+). In major tourist hubs (London, Paris, Tokyo, Sydney), acceptance is excellent. In rural areas, developing nations, or specific regions like Germany (historically cash/card-girocard heavy) or parts of Southeast Asia, you will frequently find "No Amex" signs.
Travel Strategy: Savvy travelers always carry a no-foreign-transaction-fee Visa or Mastercard as a backup when traveling internationally with an Amex.
Rewards, Benefits, and the "Premium" Positioning
Because American Express controls the full stack, they can design products with a level of integration that open-loop issuers struggle to match.
Membership Rewards (MR)
The Membership Rewards program is widely considered one of the most flexible and valuable proprietary currencies in the industry. Unlike bank points (Chase Ultimate Rewards, Citi ThankYou, Capital One Miles) which are tied to the bank, MR points are tied to the network. Key strengths include:
- Transfer Partners: Amex has a vast array of airline and hotel transfer partners (Delta, British Airways, ANA, Marriott, Hilton, etc.) often with transfer bonuses.
- Amex Offers: Statement credits for spending at specific merchants (e.g., "Spend $50, get $10 back at Dell" or "Get 20% back at Uber"). These are highly targeted and funded by the merchant/Amex partnership directly.
- Plan It / Pay It: Unique features allowing cardholders to split large purchases into fixed monthly payments with a set fee (Plan It) or pay off specific transactions instantly (Pay It).
Premium Service Ecosystem
Amex leans heavily into the "premium" brand identity.
- Centurion Lounges: Proprietary airport lounges accessible only to Platinum and Centurion cardholders. Visa/MC rely on third-party networks (Priority Pass, LoungeKey) or issuer-specific lounges (Chase Sapphire Lounges, Capital One Lounges).
- Fine Hotels + Resorts / The Hotel Collection: Exclusive
hotel booking portals offering perks like room upgrades, daily breakfast, late checkout, and property credits. Think about it: * Concierge Services: 24/7 personal assistance for reservations, event tickets, and travel planning. * Purchase Protections: Extended warranties, price protection, and return protection often exceed those offered by standard Visa/MC cards Simple, but easy to overlook..
Cost Structure
Amex traditionally operates on a dual-fee model:
- Higher interchange fees paid by merchants
- Higher annual fees paid by cardholders
This creates a self-reinforcing cycle where premium services justify premium pricing, which funds further investment in rewards and benefits.
Strategic Considerations for Consumers
When Amex Makes Sense
- High-spend individuals who can maximize rewards through travel redemptions and Amex Offers
- Frequent travelers who value airport lounge access and travel protections
- Business owners seeking expense management tools and employee benefits
- Those prioritizing customer service and dispute resolution
When to Stick with Visa/MC
- Budget-conscious users who don't want annual fees
- International travelers to regions with limited Amex acceptance
- Small business owners concerned about merchant fees deterring customers
- Everyday spending at local establishments that don't accept Amex
The Bottom Line
American Express occupies a distinct niche in the payments ecosystem. While Visa and Mastercard dominate in ubiquity and international reach, Amex excels in premium service integration and reward optimization for high-value customers. The key is understanding your spending patterns, travel habits, and tolerance for annual fees before choosing which card(s) to carry Surprisingly effective..

For many consumers, the optimal strategy involves maintaining both an Amex for its unique benefits and a no-fee Visa/MC for maximum acceptance and backup coverage. This dual-card approach allows users to make use of Amex's premium offerings while avoiding the inconvenience of declined transactions at merchants who don't accept the network.
In the long run, American Express succeeds not by competing directly with the mass-market dominance of Visa and Mastercard, but by serving a specialized segment willing to pay for enhanced value and service.
